RTF to DOCX: Convert Rich Text to Word in .NET

Rich Text Format is a plain text markup in which every style, table and image is written as control words. Word processors and older business applications produced it as a neutral interchange file, and the result is bulky and awkward to read or edit by hand.

DOCX has been the Word format since 2007 and is a compressed package of XML parts. It is smaller than the equivalent RTF, supports current styling, comments and revision marks, and is what document templates, review workflows and collaboration tools expect to receive.

GroupDocs.Conversion Cloud rewrites the source into the newer package while keeping paragraph formatting, tables, embedded pictures and fonts in position. The pairing belongs to a catalogue of more than 153 formats, and the finished document can be stamped with a watermark or protected with a password.

For a .NET application the SDK exposes the operation as an ordinary method call, with account credentials supplied once. Evaluation costs nothing while the trial lasts, the API Explorer runs the same request from a documentation page, and a single document can be handled by the browser converter.
